This oil runs $50 per GALLON and claims to be very shear stable, which it actually is as evidenced by it going from a 50wt to only a 40wt after 4200 miles of use. VERY stout additive pack as well!
It also holds shift quality incredibly well with zero notchiness between gears and ease of finding Neutral. Once I'm done with my remaining Rotella stash, I'm probably going to go back to this stuff and change the oil every 2 years since it can hold up.
Previous UOAs from Blackstone below showing how aggressively this motor shears oils.
